Abstract
The invention provides a kind of C6678 Ethernet loading methods of IP address flexibility and changeability, it is related to technical field of information processing.Methods described includes the MAC Address that host computer extracts the C6678 in the BOOT bags sent by the C6678 by network packet capturing mode, afterwards, simulation generation arp response bags, the C6678 to be placed IP address is included in the arp response bags, and the IP address after setting and the C6678 MAC Address are established into dynamic corresponding relation, finally in a broadcast manner by IP address notify corresponding to C6678, so as to will loading image file the C6678 is sent to by network udp protocol.According to the method, arp ponds are configured using dynamical fashion, each IP has ageing time, and effective arp parsings address can be produced in time after changing board or modification IP, solves in the prior art because the situation that IP address conflict causes loading to fail occurs.
Description
Technical field
The present invention relates to technical field of information processing, and in particular to a kind of C6678 Ethernets of IP address flexibility and changeability add
Support method.
Background technology
The TMS320C6678 (referred to as C6678) of Texas Instruments (Texas Instruments, abbreviation TI) company
It is that domestic embedded high-performance calculating field uses wide multinuclear digital signal processor (DSP) chip after 2014.
The handbook SPRUGY5B of TI companies《KeyStone Architecture Bootloader User Guide》,
Refer to that C6678 there are a variety of load modes in June 2012, JTAG (debugging test interface), Ethernet (ether can be passed through
Net, abbreviation ETH), PCIe (PCI Express buses), SRIO (high-speed serial bus), SPI (Serial Peripheral Interface (SPI)), I2C (two
Wire type universal serial bus) etc. interface load software.TI companies be integrated with C6678 RBL (ROM Boot Loader, it is built-in plus
Carry core), corresponding loading mode can be entered according to the input selection of outside, receive and perform application software code.
Wherein, TI provides two kinds of Ethernet load modes：
1) it is a kind of to be based on UDP host-host protocols
Be specifically shown in multi-Core Development bag MCSDK tools boot_loader examples ethernet.
Process to PC after electric on DSP or reset as shown in figure 1, send BOOTP load request bags, for stating DSP MAC
Address；After PC receives BOOTP, DSPMAC and IP corresponding relation is added in ARP address resolution pond by arp-s instructions；
DSP loading image is sent to DSP by network interface udp protocol.
This mode, there is Railway Project：
A) need manually to have seen whether BOOTP bags on PC；
B) need to call arp-s to instruct with administrator right；
C) arp-s instruction addition be static address, will not aging, when change board or modification IP after, address can be triggered
Conflict, loading is caused to fail.
2) it is another to be based on TFTP (Trivial File Transfer) agreement
Be specifically shown in multi-Core Development bag MCSDK tools boot_loader ibl.
As shown in Fig. 2 PC needs to start TFTP services, the upper electricity of DSP or the backward PC of reset require to transmit a certain finger process
Determine the file of IP address, when it is determined that there is file, then this document is transferred in DSP.
This mode, there is also some problems；
A) DSP IP address be burning in the EEPROM of I2C EBIs, it is that is, fixed, to change IP address
Must be very inconvenient using JTAG emulators again burning EEPROM；
B) as can be seen that this mode is come leading by DSP, host computer can not control DSP specific loading procedure.
The content of the invention
In order to solve the above problems, the invention provides a kind of C6678 Ethernet loading methods of IP address flexibility and changeability,
By PC control DSP loading procedure, make IP address variable at any time, and without JTAG emulators, without administrator right.
The C6678 Ethernet loading methods of IP address flexibility and changeability of the present invention, are mainly included the following steps that：
Step 1: connect the C6678 and host computer；
Step 2: the load mode of the C6678 is arranged to Ethernet loading；
Step 3: to electricity on C6678 or reset；
Step 4: the host computer is extracted in the BOOT bags sent by the C6678 by network packet capturing mode
C6678 MAC Address；
Step 5: simulation generation arp response bags, the arp response bags include the C6678 to be placed IP address,
And the IP address after setting and the C6678 MAC Address are established into dynamic corresponding relation；
Step 6: the arp response bags are sent to C6678 in a broadcast manner；
Step 7: host computer is sent to the C6678 by image file is loaded by network udp protocol.
Preferably, the network packet capturing is realized using WinPcap function libraries.
Preferably, the arp response bags are realized using WinPcap function libraries.
Preferably, four-step 7 of repeat step, until all C6678 in array load completion.
Preferably, using multithreading, according to step step 4-step 7, complete all C6678's in array
Loading.
Advantages of the present invention：
1) loading velocity is fast
Host computer can make full use of the transmission bandwidth of gigabit Ethernet using multithreading, and multiple DSP are loaded simultaneously,
As loaded 12 DSP simultaneously, take and be no more than 3 seconds.
2) IP address sets flexible
Host computer has ageing time using dynamical fashion configuration arp ponds, each IP, change after board or modification IP can and
When produce effective arp parsing address.
3) without JTAG emulators
IP address etc. is changed completely without JTAG emulators, convenient use.
It present invention can be suitably applied in the embedded information processing system using TMS320C6678DSP, such as Aeronautics and Astronautics, ship
The fields such as oceangoing ship, communication, software radio, artificial intelligence.
